Perhaps rules is too harsh of a word.
That being said I have two simple rules when it comes to reading
1. No dogs. I do not read books about dogs. I do not care if it’s a happy book about dogs. No dogs. The dog always dies. Each and every time! No matter what! Even if it lives to a ripe old age of 150 in dog years. After the book, I am left in a puddle of tissues, red faced balling my eyes out and unable to sleep. No dogs ever. Or cats or elephants or ducks or tigers for that matter. Just no animals.
2. I stop reading if I don’t like the book after the 2nd chapter. I’ve been told this is one wasteful and two what if it gets better. It won’t. It rarely does. It must be noted that there is a difference between a slow start and just bad writing. A slow start I can handle. Bad writing is a no go.
2.5 Ok maybe I have three… we will just go with 2.5. I rarely read books about war or soldiers. Just not my jam nor my cup of tea.
Do other people have reading rules when it comes to picking out books?
